I haven't finished the range, and have found a few cycles. This is the only one with the star at the end of the line, so I was wondering if it means something different, and what if it does.

22127-1-1 mod 19396094914493492417412352623610788052879 is 12878846122774700542942977398640678236037, so no, it's not a factor.
